Centrist is the wrong word, I am not really in the center on any single issue, I just do not agree with either side on most issues.
More personal freedom.
The right to marry the consenting adult you wish to marry. The right to run your business as you wish. The right to smoke a joint instead of drinking a 5th of Jack if that is what they want to do. Just to name a few.
On the flip side a smaller, less expensive Govt. We are 32T in debt as a nation due to out of control spending all while brining in record revenue each and every year. This is unsustainable.
Less Government intrusion in our lives. The Govt should not be deciding what is "truth" and what is not ,what books we can read, and more.
